ROAD-MACHINE.

Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed November 20, 1913. Serial No. 802,130.

To all lwhom t may concern.'

Be it known that I, JAMES M. BRESEE, a citizen of the United States, residing at Mattoon, in the county of Coles and State of llinois, have invented certain new and useful Improvements in Road-Machines, of which the following is a specification.

This invention relates to improvements in road machines, and has for its principal object to provide such a machine having improved means for raising, lowering and adw justing the position of the scraper bars andl which the means for controlling` the scraper bars are all located in convenient position for handling by one operator without necessity for his moving from a comparatively limited space.

These and other objects are set forth'in the following specification and shown in the accompanying drawings, in which:

Figure 1 is a plan view of my machine; Fig. 2 is a front elevation of the same; Fig. 3 is a detail section taken along the line 8 3 of Fig. 4; Fig. 4 is a side elevation of my -machineg Fig. 5 is a detail of the locking mechanism; Fig. 6 1s a detail of the arm andA scraper bar construction showing the scraper bars in section; Fig. 7 is a side elevation of the same; Fig. 8 is a detail section along the line 8 of Fig. 4; Fig. 9 is a detail showa locking member in non-locking position.

Like numerals refer to like elements throughout the drawings, in which 1 and 2 designate scraper bars,v one on each side of the machine, said bars being capable of being spread apart a considerable distance at their forward ends and converging in such position at their rear ends when operating on wide roads. The amount of extension or spreading of the Scraper bars maybe adjusted according to the varying widths of the roads on which my machine is used, as desired.

To maintain the bars in spread relation, I provide links or arms 3 and 4 which bend over at one extremity and are pivotally attached to a respective scraper bar 5 and 6, as shown in Fig. 2, for example.V These arms 3 and 4 extend upwardly from the scraper bars over the body of the machine and are pivotally secured together at their inner extremities by a pin 7, projecting through eyes or holes in the flattened ends 3a and 4aL respectively, of arms 8 and 4. Upwardly of the portions 3a, 4a, the pin 7 is reduced in diameter to form a shoulder 7a, and terminating in threadedportion 7b for engagement by nut 23. Lying upon the upper arm 4', upon the flattened portion 4a thereof is a plate 17, suitably apertured to permit insertion therethrough of the reduced portion of pin 7 and contacting with and supported on shoulder 7a thereof. Located upon the plate 17 is the angle 21 having the flange 21a secured to the plate 17 by nut 23. It will be apparent that this nut will serve to securely clamp plate 17 in position against the shoulder 7a of pin 7. Longitudinally arranged channel beams 9 and 10, having their channels inwardly turned and spaced apart, as shown in Fig. 8, for example, are carried by the machine andare secured to and suitably braced by means of. brace members 11, 12, extending from the main longitudinal beams A, B,v

of the body of the machine. The channel beams 9, 10, are provided with the inwardly turned upper flanges 9a, 10a, respectively,

upon which lies the flattened portion 3a off the lower arm 3 of arms 3 and 4. rFhe flanges 9a, 10a are spaced apart sufciently to permit the sliding therebetween of the pin 7. A plate 8 is carried upon the head 7 c of the pin 7 in sliding'contact` with the under surfaces of flanges 9a, 10a, being formed on its upper surface to it the 'contour of the lower surfaces of such flanges. It will be apparent that this construction is adapted to permit sliding ofthe arms relative to the track members 9', 10, Vwithout permitting their displacement therefrom, the pin 7 and nut 23 serving to prevent clamping or4 binding of the plates -and arms to the track` members. Pins 18,19 located on either side of the pin 7, extendbetween the plates 8 Uprights 29 are secured to the Channel bars 9, 10 by rivets or the like through their flanges 29a, and extend upwardly of the said track members, as clearly shown in Fig. 8, adjacent each end of the track. Cross bars 27 extend across between the tops of the up rights 29. A locking bar 30 extends between the cross bars 27, and is provided with studs or lugs at each end, indicated by numerals 30a, these studs being pivotally mounted in suitable apertures in the cross bar 27. This locking bar 30 is preferably T-shaped and provided with the main flange 30" and cross flange ,309 The upright flange 30h is notched as indicated by numerals 24, these notches being arranged for engagement with the upright flange of locking member 21, as clearly shown in F ig. 5.

An operating lever 3 1 is secured to and extends upwardly from the cross flange 30C of locking bar 30 and is located preferably adjacent one end thereof. It will be appar ent that this lever may be moved to partially rotate the locking member 30 so as to cause disengagement of the notches 241: with the locking member 21, so that the ends of the arms 3 and 4 may slide relative to the track, as desired. In order to maintain the locking bar in locking or non-locking position, I may thread one end of the stud 30a and provide a nut 30 thereon, a washer 30 being located between the nut and the cross bar 27 so that tightening of the nut 30 will press the washer 30 against the said cross bar increasing the frictional contact therewith so that while rotation of the locking bar 30 will be permitted, it will be retained in an adjusted position.

The arms 3 and 4, as stated above, are bent rover the scraper bars 1 and 2 and bent back thereto as indicated by numerals 3b, 1lb, respectively, being pivoted at their extremities to the scraper' bars, as clearly shown in Fig. 6, for example, a pin 84 being inserted through an aperture in the extremity of the respective arm and serving to secure the same between the parallel flanges of angle bars S5, S6, each of which has a flange secured to a channel bar 87, which in turn is secured by angles 8S to the curved scraper blade 89. A strap is secured around the bent portion of the bars 3 and el, as shown in Figs. 6 and 7, and serves to strengthen and reinforce the same.

Carried by the body members A, B, adjacent their rearward portion. are the supporting braces 0,1), providing an upwardly extending support for the pulley 71, over which extends an operating cable or chain G6, to and partially around a second pulley 72, which is rotatably connected to the chain 72a, secured at its spaced apart extremities to a cross bar 73, to which in turn are pivotally secured, adjacent their rear extremities, the scraper bars 1 and 2. One end of this cable or chain is secured to the supporting structure C, D, and the other end extends longitudinally of the machine to a drum mounted upon shaft 68, extending upwardly of the body and provided with the operating handle wheel 68, rotation of which will-raise or lower the rear portion of the scraper bars. This being a well-known construction and forming no part of my present invention, it will not be necessary to more fully describe the same. Chains 77, 7S extend from the cross bar 73 to the body of the machine, and are secured thereto. rlhese chains are relatively crossed, and thereby serve to resist lateral swaying or ino-vement of the scraper bars 1 and 2.

Adjacent the forward portion of the body of the machine are located raising and lowering members 34, 35, shown as U-shaped, being in effect of yoke-like construction. These yokes are pivotally attached at their free ends to the body members A, B, respectively, and are provided with pulley blocks d'2, 4B, respectively, pivotally mounted adjacent the upper portion of the yoke. @perating cables or chains extend around the respective pulleys in these blocks to and around pulleys 54, 55, respectively, secured to the bars 1 and 2, and from thence extend upwardly to and around other pulleys in the blocks 112, 113. They then extend downwardly to and are secured to the eye-bolts 5G, 57 carried by the cross beam 81. At their other ends these cables or chains are wound around drums 58, 59, pivotally supported between uprights 58, 59a, which, in turn, extend upwardly from and are secured to the extremities of cross beam S1. rthis cross beam is supported upwardly of the body of the machine by uprights 82, which are themselves secured to the longitudinal frame members A, B, as shown in Fig. 2. Rods 58h, 59h extend between the pairs of uprights 58a, 59a, respectively, upwardly of the drums 58, 59. Hand wheels 60, 61, are mounted upon the shafts of the drums 58, 59, respectively, and pawl and ratchets or similar mechanisms G2, 63, are provided for locking the drums 58 and 59 in desired position. Shackles or eye bolts 3451, 35a are provided in the upper portions of the yokes 34, 35, and cables or chains extend therefrom to and around a drum 46, carried between uprights 46a extending upwardly from the cross beam S1. A hand wheel 47 is operatively secured to this drum 46 and a Suitable paWl or ratchet or similar mechanism is provided therefor. Rotation of the hand wheel 47 will operate to simultaneously raise or lower the two yokes 34, 35, as desired, and they may be held in adjusted position by the pawl and ratchet 46h.

l It will be apparent that in the operation ot' my improved device, assuming the same is in operative position relative to the road upon which it is to be used, the pawl and ratchet 4G" may be rthrown out of engagement to release the drum 46 and thereby lower the yokes 34, $35 to the desired position. At the same time the operating lever 3.1. may be moved to the position indicated in Fig. 9, thereby permitting free sliding of the ends Iof the arms 3 and 4. The ratchet G9 may then be released from engagement with the pawl 70, permitting the drum 67 to unwind and allowing the rear portion of the scraper bars to be lowered to the road. Similarly drums 58 and 59 may be vreleased to permit the front portion of scraper bars to contact with the road and to move to operative position. The contact be tween the road and the scraper bars will operate to spread the latter to the greatest possible width permitted by the adjustments and by the amount of cable or chains 52, 53, unwound, thereby permitting adjustment for variation in the width of the road. A certain amount of lateral adjustment may be also made by means of raising or lower` ing the yokes 34, 35. It is to be notedthat when the bars have spread to the position desired, the lever 31 may be raised to an upright position, thereby causing the corresponding of the notches 24 on bar 30 to engage with the member 21 to thereby prevent further lateral movement of the scraper bars. This insures rigidity of the latter with re spect to the road when in operation thereon. To move the bars to inoperative position, 'it is only necessary to reverse the above movements, it being noted that suiiicient play and flexibility is present in and between the link arms to permit raising and lowering of the scraper bars.

It will be apparent'that I have provided' a simple and etlicient form of road machine, capable of ready and quick adjustment to desired position. It will also be apparent that my device is susceptible of many changes and modiifications and I do not wish to be restricted to the form shown or described, beyond the scope of the appended claims.
